The Maxwell’s needle with two solid cylinders can be used for the purpose of verifying the theorem of parallel axis. The two weights are symmetrically placed in the tube on either side of the axis of rotation and their positions are noted down on the scale engraved by the side of the groove on the hollow brass tube as shown...

Balfour Stewart and William Winston Haldane Gee designed an instrument to study the variation of magneticfield along the axis of a circular coil. It consists of a coil with specified number turns of copper wire and acompass that can be moved along the axis of the coil. This simple apparatus is still in use in most physics labs. ..
